Richard Kemper, a Hillsborough County middle school teacher was among 13 people who were arrested in an internet prostitution sting in Polk County.
The Polk County Sheriff's Office said the popular classified Web site Craigslist targeted men who used the site to look for sex. They were then lured to an undercover house in Winter Haven.
Kemper, 50, was arrested after he offered an undercover agent $ 150 for sex. A software developer, paint-store manager, citrus buyer and truck driver were others arrested.
Polk County Sheriff Grady Judd said, "Our message is pretty straightforward, if you want to engage in prostitution, stay out of our community."
